The pressure versus temperature graph of an ideal gas is as shown in the figure. The density of the gas at point \(A\) is \({\mathit{\rho}}_{0}\). Density at point \(B\) will be:
| 1. | \(\dfrac{3}{4}{\mathit{\rho}}_{0}\) | 2. | \(\dfrac{3}{2}{\mathit{\rho}}_{0}\) |
| 3. | \(\dfrac{4}{3}{\mathit{\rho}}_{0}\) | 4. | \(2{\mathit{\rho}}_{0}\) |
